In addition to its regular full-time staff, Redemption Christian Academy has a number of professionals including business men and women, entrepreneurs, inventors, artists, college educators, and retirees who volunteer as teaching faculty and guest lecturers. All work together diligently to educate each RCA student's heart, head, and hands. "An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you do know and what you don't... It's knowing, where to go to find out what you need to know; and it's knowing how to use the information you get" (William Feather).
